1. When will the SDK v1.4 be released?
2. Will it be compatible with 4850x2
3. Will it be compatible with 2x (4850x2) in a system?
Thanks so much for sharing your thoughts.
1. In March.
2. We plan to test against 4870X2; i think it is safe to assume 4850X2 will also work.
3. Should work.
Please note that all the above are forward looking statements from me and not guarantees from AMD.
Unfortunately, no. This feature has been at the highest priority level since the 1.3 dev cycle, but we encountered some issues that prevented its completion within our timeline for 1.4.
I have gone through the pain of working around this -- by hard-coding each element of the local array (eg, a0, a1....,a19 instead of a). For now, that may act as a stone-age workaround for local arrays.
For example, I had to sort 25 values in my kernel.
for (k = 0 to 23)
for (l = k+1 to 24)
Instead, I unrolled the loop
float buf00, buf01, ... , buf24;
Very painful, but it did the job. And faster than a for-loop would have been.
will AMD Stream 1.4 contain the CAL OpenGL Extension headers?
..and some documentation added to the programming guide like for DirectX interop..?
I say that because CAL returns that CAL OpenGL extension is supported
(at least on catalyst 9.1 using Lavalys Everest 5.00) ..
if not can somebody post an expected timeframe..
at least I hope that will be added to OpenCL SDK as is layered on top of CAL and has
